Definition: What Does “Curious About” Mean?
Before comparing curious of vs curious about, let’s define the expression.
Curious About Definition
Curious about (adjective + preposition)
Meaning:
Wanting to know, learn, explore, or understand more about a person, object, event, topic, or situation.
This is the standard curious about definition used by native speakers and English learners alike.
Curious Meaning in English
The curious meaning in English is:
Eager to know or learn something.
Someone who is curious enjoys asking questions, discovering new information, and understanding how things work.
For example:
- Children are naturally curious.
- Scientists stay curious throughout their careers.
- Good writers remain curious about people and ideas.
Why Do We Say “Curious About”?
Many learners ask, why do we say curious about instead of curious of?
The answer lies in English grammar.
The adjective curious naturally pairs with the preposition about. This combination is known as a collocation, which means certain words naturally go together.
For example:
- interested in
- excited about
- worried about
- responsible for
- famous for
- curious about
Learning these adjective and preposition combinations is an important part of mastering English.
This is why curious about sounds natural in both spoken English and written English.
Grammar Rule
A simple grammar formula makes this easy to remember.
Curious + About + Noun
Examples:
- curious about science
- curious about history
- curious about your family
- curious about the future
- curious about the project
Curious + About + Question Word
Examples:
- curious about why it happened
- curious about how it works
- curious about where they live
- curious about when the meeting starts
- curious about who called
If you remember this simple formula, you’ll almost always choose the correct expression.
Is “Curious Of” Correct?
A common question is:
Is curious of correct?
Technically, yes—but with an important warning.
The phrase curious of appeared in older English literature several centuries ago. You may still find it in historical books, classic novels, poetry, or archived documents.
For example:
The traveler grew curious of the strange village.
Although readers can understand the sentence, modern English would naturally say:
The traveler grew curious about the strange village.
Today, curious of is no longer considered the standard choice. Most dictionaries, grammar references, editors, teachers, and style guides recommend curious about instead.
So, while curious of meaning can still be understood in historical contexts, it isn’t the expression most native speakers use today.
Can You Say “Curious Of”?
Yes, you can—but only in limited situations.
If you’re writing:
- historical fiction
- classic literature
- poetry
- period dramas
- texts that intentionally imitate older English
then curious of may sound appropriate.
However, if you’re writing:
- blog posts
- business emails
- essays
- school assignments
- website content
- social media posts
- professional documents
always choose curious about.
For modern communication, curious about is the safer and more natural option.
